Air pollution and health

Air pollution can occur anywhere. It occurs when the environment is contaminated by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Stoves in the home, motor vehicles, industrial facilities and forest fires are common sources of air pollution.
Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide. Both ambient (outdoor) and household (indoor) air pollution cause respiratory and other diseases, which can be fatal.
